The external type is not associated with a traumatic event, but mostly with a minor mechanism of injury. The clinical presentation is often easily observable by observing and listening for snap as the patient actively flexes and extends the [[hip]]. These patients may describe a sense that the [[hip]] is [[Hip Dislocation|dislocating]]. People with external SHS may also have coxa vara, fibrotic scar tissue, a prominent greater trochanter, smaller lateral pelvic width, or a past surgery for anterolateral [[knee]] instability. {{#ev:youtube|wiWHd_j7aX0}}Hinojosa T. EBP - Snapping Hip. Available from https://www.youtube.com/watch?v=wiWHd_j7aX0 (accessed 15/11/2020). === Internal SHS === Internal SHS also has a gradual onset, not usually associated with a traumatic event. These patients describe a painful sensation coming from deep within the anterior groin as they move their [[hip]] from flexion into extension or external rotation. The snapping movement can produce an auditory clunk or click. === Intra-articular SHS === Patients with intra-articular SHS report a sudden onset of snapping or clicking from an injury or traumatic event to the [[hip]] capsule. The sources of this snapping can come from intra-capsular lesions, loose bodies settling in the acetabular fovea or synovial folds, a [[Labral Tear|torn acetabular labrum]], synovial chondromatosis, or a history of habitual [[Hip Dislocation|hip dislocation]] in children or idiopathic recurrent subluxation.
